Common Antonovka is a Russian apple that has been grown for centuries, but was first recorded in Kursk in 1828. This apple is so popular that there is a monument to it in Kursk.
Can be very tart if not allowed to ripen fully, but if ripened fully, it will be sweet with high acidity. Good for cooking, fresh eating.
This heirloom is extremely winter hardy (hardy to zone 3), drought hardy, and stores well.
